Living in the UK I never thought I'd write this but today the very unusual combination of high temperature and high humidity meant that when I tried to apply matt varnish to some newly finished figures they dried with a slight satin sheen. Most annoying! Lots of rework required.
I've read numerous blog and forum posts from people in America who've been affected by high humidity and temperatures when using a spray varnish. Given the more moderate climate here in the UK, I never expected this to bother me; especially as I only ever use a "brush on" varnish. However, it's the only thing I can think of that could have caused the problem.
I suppose I should have seen it coming. It's already the hottest UK summer since 2006, today has been one of the hottest of the year so far and the forecast for tonight is for thunderstorms due to the high humidity.
So it looks like I won't be varnishing anything until well in to next week when the humidity is due to drop.
